BACKGROUND 1. Technical Field

Exemplary embodiments of the present invention relate to compliance-based cleaning of equipment, and more particularly, to a device, system and method of compliance-based cleaning of equipment.

2. Discussion of Related Art

There are many environments in which it is desirable to clean (e.g., disinfect and/or sterilize) tools or equipment. For example, in a medical environment such as a doctor's office, hospital, ambulatory surgery center, nursing facility, rehabilitation facility, etc., it is necessary to clean equipment to prevent the spread of germs, bacteria, viruses, fungus, etc., and to guard against, limit or prevent hospital or facility acquired infection.

Recent studies have suggested that during a patient examination, the chestpiece of a medical practitioner's (e.g., a doctor, nurse, physician's assistant, etc.) stethoscope, which is the portion that comes into contact with a patient's skin, typically acquires more germs, bacteria, viruses and fungus than any part of the medical practitioner's hand other than his or her fingertips. As a result, using the same stethoscope on different patients without cleaning the stethoscope between examinations poses a serious risk of spreading germs, bacteria, viruses, fungus, etc., and causing hospital or facility acquired infection.

In an effort to guard against, limit or prevent the spreading of germs, bacteria, viruses, fungus, etc. between patients, disposable stethoscope covers (e.g., cloth or barrier film covers) are sometimes used on the chestpiece of a stethoscope between examinations. However, the use of a stethoscope cover may actually result in the introduction of additional bacteria through the covers, and also may negatively impact the functionality of the stethoscope. Moreover, the ability of a medical practitioner to perform an effective examination with the stethoscope, despite the impaired or reduced functionality of the stethoscope as a result of covering the chestpiece, is extremely variable and is affected by the practitioner's skill, experience, and hearing, which may in turn be affected by aging related changes. Adverse consequences from covering the stethoscope, coupled with increased legal liability risk attendant thereto, suggest that covering the stethoscope is a poor substitute for cleaning it in a fashion which can be verified and documented. In addition, medical practitioners frequently forget or neglect to use or change covers, and may feel a false sense of safety through use of the covers, resulting in the stethoscopes being cleaned less frequently.

Finally, most if not all manufacturers of stethoscopes warn against covering the chestpiece when in use. Regularly cleaning the chestpiece of a stethoscope between all patient examinations is typically thought to be the most efficient way to guard against, limit or prevent the spreading of germs, bacteria, viruses, funguses, etc. However, medical practitioners frequently forget or neglect to perform this cleaning, regardless of whether stethoscope covers are being utilized. Given the risk of hospital or facility acquired infection, some medical practitioners opt to forego the stethoscope examination entirely. Even when they have the means to clean the stethoscope, medical practitioners often find that those means are not conveniently placed at or near the hand hygiene dispenser.

Like reference numerals may refer to like elements throughout the accompanying drawings. It will be understood that elements shown in the drawings may not be drawn to scale, and the size of elements in the drawings may be exaggerated for clarity.

Exemplary embodiments of the present invention provide a system and device for implementing compliance-based cleaning. Herein, the term cleaning may refer to disinfecting and/or sterilizing.

For convenience of explanation, exemplary embodiments of the present invention are described herein with reference to a compliance-based cleaning device, system and method to clean a stethoscope in a medical setting (e.g., a hospital, ambulatory surgery center, nursing facility, rehabilitation facility, doctor's office, operation room, intensive care unit (ICU), emergency room, medical center, etc.). However, it is to be understood that utilization of the compliance-based cleaning device, system and method with a stethoscope is merely exemplary. That is, the compliance-based cleaning device, system and method according to exemplary embodiments is not limited to use with a stethoscope, nor is it limited to a medical setting. For example, exemplary embodiments of the present invention may be applied to any tool/device/equipment that is to be cleaned, and that is capable of being identified by a readable indicia such as, for example, a serial number, a registration number, a barcode, an NFC tag, etc., in which the readable indicia stores/includes a unique identifier capable of uniquely identifying the tool/device/equipment. For example, it is to be understood that when a chestpiece of a stethoscope is herein described as undergoing a cleaning process, the cleaning process may be performed on the targeted portion of any other piece of equipment (or the entire piece of equipment) being cleaned in accordance with exemplary embodiments of the present invention. Further, it is to be understood that the readable indicia may form the basis for a database of such tool/device/equipment such as, for example, by the medical practitioner registering the readable indicia of the stethoscope with the hospital, facility or office, so that the stethoscope is identifiable as the stethoscope utilized by the specific medical practitioner, as described in further detail below.

Further, it is to be understood that exemplary embodiments of the present invention may be used in any setting, including non-medical settings. Referring to a medical setting, in addition to stethoscopes, exemplary embodiments may also be utilized with, for example, blood pressure cuffs, hemodialysis machines, X-ray machines, thermometers, hospital pagers, endoscopes, manual ventilation bags, CPR manikins, ultrasound instruments, reusable transducer heads, glucometers, and blood pressure machines. It is to be further understood that exemplary embodiments of the present invention do not rely upon the present existence of readable indicia, as readable indicia may be added to tools/devices/equipment such as, for example, the addition of a readable indicia (e.g., a serial or registration number, an NFC tag, etc.) by the manufacturer or the addition of a readable indicia or differentiating mark or symbol by the owner or user. It is to be understood that exemplary embodiments of the present invention may be used in cleaning, disinfection and/or sterilization devices to capture readable identifiers of some or all of the tools/devices/equipment being cleaned, disinfected or sterilized in one or a series of processes. Therefore, the present invention may be added to, or incorporated into, existing cleaning, disinfection and/or sterilization equipment.

Herein, the term medical practitioner refers to any person providing medical services to a patient including, for example, a doctor, nurse, physician's assistant, etc. The term user refers to any person using a compliance-based cleaning device or system according to exemplary embodiments of the present invention, including a medical practitioner in a medical setting or a non-medical practitioner in a non-medical setting.

FIG. 5 is a block diagram illustrating a compliance-based cleaning device according to an exemplary embodiment of the present invention

The compliance-based cleaning device 100 of FIGS. 1A-1B is configured to receive a portion of a stethoscope 101. For example, the compliance-based cleaning device 100 may include a receiving area 102 shaped and dimensioned to receive the chestpiece 103 of the stethoscope 101. The chestpiece 103 includes the bell and the diaphragm of the stethoscope 101.

The chestpiece 103 of the stethoscope 101 may also be referred to herein as the head of the stethoscope 101. The receiving area 102 is shaped and dimensioned to receive a standard size chestpiece 103. For example, most commonly used stethoscopes, including both stethoscopes commonly used for infants and adults, have a diameter between about 1 inch and about 3 inches. Accordingly, the receiving area 102 of the compliance-based cleaning device 100 may include an opening in which the chestpiece 103 is inserted that has a diameter in the range of about 1 inch to about 3 inches or greater. According to an exemplary embodiment, the opening of the receiving area 102 may be about 3 inches or greater, which permits the compliance-based cleaning device 100 to be used with a variety of stethoscopes having differently sized chestpieces. Alternatively, in an exemplary embodiment, the opening of the receiving area 102 may be designed to receive a chestpiece 103 having a specific size such as, for example, a chestpiece having a diameter of about 1.7 inches.

It is to be understood that the receiving area 102 according to exemplary embodiments designed to receive equipment other than the chestpiece 103 of a stethoscope 101 is shaped and dimensioned to receive the piece of equipment to be cleaned. That is, the receiving area 102 is not limited to the size and shape shown in the exemplary embodiment of FIGS. 1A and 1B. For example, it is to be understood that exemplary embodiments are not limited to the slot-shaped receiving area 102 that is shaped and dimensioned to receive primarily the chestpiece 103 of a stethoscope 101, as illustrated in FIGS. 1A-1B. For example, as shown in FIGS. 1C-1D, in an exemplary embodiment, instead of a slot-shaped receiving area 102, the compliance-based cleaning device 100 may include a cavity as the receiving area 102. The cavity-based receiving area 102 may be larger than the slot-shaped receiving area 102. As shown in FIGS. 1C-1D, the receiving area 102 may be accessed via a lid 123 disposed, for example, at an upper portion of the compliance-based cleaning device 100. A seal 124 may be utilized with the lid 123 to create a sealed coupling between the compliance-based cleaning device 100 and the lid 123. For example, the piece of equipment to be cleaned may be entirely placed within the receiving area 102, the lid 123 may be closed to seal the receiving area 102, and the cleaning process may then be performed on the piece of equipment. As shown in FIGS. 8 to 26 , an embodiment of the compliance-based cleaning device 100 does not include the receiving area 102 that receives primarily a chestpiece 103 of the stethoscope 101, but rather, includes a cleaning area 803 which may receive an entire stethoscope 101, as described further below with reference to FIGS. 8 to 26 .

Due to the large size and the shape of the receiving area 102 in an exemplary embodiment according to FIGS. 1C-1D, a single compliance-based cleaning device 100 may be utilized to clean a variety of pieces of equipment. For example, a single compliance-based cleaning device 100 may be used to clean stethoscopes, blood pressure cuffs, thermometers, hospital pagers, endoscopes, etc. It is to be understood that, other than the shape, size and structure of the receiving area 102, all or some of the components and capabilities of the compliance-based cleaning device 100 shown in and described with reference to FIGS. 1A-1B (as well as FIG. 1E) may also be included in the compliance-based cleaning device 100 of FIGS. 1C-1D.

Referring again to FIGS. 1A-1B, since the chestpiece 103 of the stethoscope 101 is the portion of the stethoscope 101 that typically comes into direct contact with a large number of patients, the chestpiece 103 typically includes the largest amount of germs, bacteria, viruses, fungus, etc. relative to the rest of the stethoscope 101. Thus, the chestpiece 103 is the portion of the stethoscope 101 for which cleaning is most important. According to the exemplary embodiment shown in FIGS. 1A-1B, the receiving area 102 of the compliance-based cleaning device 100 is shaped and dimensioned to receive primarily the chestpiece 103 of the stethoscope 101. For example, the receiving area 102 is not shaped and dimensioned to receive the earpieces and/or the tubing of the stethoscope 101 (although a small amount of the tubing near the chestpiece 103 may enter the receiving the area 102 along with the chestpiece 103). This configuration allows for the chestpiece 103 to be adequately cleaned without potentially damaging the tubing and/or the earpieces of the stethoscope 101 as the result of unneeded cleaning of these components. Alternatively, according to exemplary embodiments, the entire stethoscope 101 may be placed within the receiving area 102 (see, for example, FIGS. 1C-1D).

According to an exemplary embodiment of the present invention, the compliance-based cleaning device 100 performs a cleaning process using a liquid cleaning solution. Herein, the term cleaning process refers to the period in which the piece of equipment being cleaned (e.g., the chestpiece 103 of the stethoscope 101) is disposed within the receiving area 102 of the compliance-based cleaning device 100 and is being cleaned by, for example, being exposed to the liquid cleaning solution or ultraviolet rays, as described below. In addition, exemplary embodiments may utilize a brush or a plurality of brushes 126 (see FIG. 2A) or other surface for physically wiping the piece of equipment being cleaned. These cleaning processes may be separately implemented or combined into a single compliance-based cleaning device 100.

Exemplary embodiments in which the cleaning process is performed using a liquid cleaning solution are described herein.

The duration of the cleaning process may vary according to exemplary embodiments of the present invention. For example, in an exemplary embodiment, the duration of the cleaning process may be between about 30 seconds and about 60 seconds, resulting in a significant reduction of microbial population on the chestpiece 103. In other exemplary embodiments, the cleaning process may be shorter (e.g., less than about 30 seconds) or longer (e.g., up to about 2 minutes or longer). The compliance-based cleaning device 100 may include a cleaning member 104 and a cleaning solution chamber 105. The cleaning member 104 is connected to the cleaning solution chamber 105. The cleaning solution chamber 105 stores a liquid cleaning solution used to clean the piece of equipment (e.g., the chestpiece 103 of the stethoscope 101) once the piece of equipment (e.g., the chestpiece 103) has been inserted into the receiving area 102 of the compliance-based cleaning device 100. For example, once the piece of equipment to be cleaned (e.g., the chestpiece 103) has been inserted into the receiving area 102, the liquid cleaning solution is passed from the cleaning solution chamber 105 to the cleaning member 104, and the cleaning process is performed.

The liquid cleaning solution may be any type of solution capable of cleaning the piece of equipment. For example, the cleaning solution may include, but is not limited to, a germicidal compound, hydrogen peroxide, peracetic acid, alcohols (e.g., ethyl alcohol, isopropyl alcohol (e.g., about 70% to about 90% isopropyl alcohol), methyl alcohol, etc.), chlorine and chlorine compounds, formaldehyde, glutaraldehyde, ortho-phthalaldehyde, iodophors, phenolics, quaternary ammonium compounds, or a combination thereof. Alternatively, exemplary embodiments may use means other than a liquid cleaning solution to clean the piece of equipment (e.g., the chestpiece 103), such as, for example, an ultraviolet light (see FIG. 2C) and/or a brush 126 (see FIG. 2A).

The cleaning solution chamber 105 passes the liquid cleaning solution stored therein to the cleaning member 104. The cleaning member 104 is located in proximity to the receiving area 102 of the compliance-based cleaning device 100. For example, the cleaning member 104 may be located within the receiving area 102 or adjacent to the receiving area 102. The cleaning member 104 may include, for example, a plurality of holes 106, as shown in FIG. 2B. The liquid cleaning solution may be sprayed onto the piece of equipment (e.g., the chestpiece 103) through the plurality of holes 106 to clean the piece of equipment (e.g., the chestpiece 103). For example, a mist formed from the liquid cleaning solution may be sprayed onto the chestpiece 103 through the plurality of holes 106 to clean the chestpiece 103. Utilization of the plurality of holes 106 allows for the chestpiece 103 to be cleaned without submerging the chestpiece 103 in the cleaning solution, thus, permitting the chestpiece 103 to be cleaned without being damaged.

Exemplary embodiments in which the cleaning process is performed using ultraviolet light are described herein.

According to an exemplary embodiment of the present invention, the cleaning device 100 performs a cleaning process using a light-emitting device (e.g., a light-emitting diode (LED)) that irradiates the piece of equipment (e.g., the stethoscope 101) with ultraviolet light. For example, exemplary embodiments utilize ultraviolet germicidal irradiation (UVGI) to clean the piece of equipment (e.g., the chestpiece 103 of the stethoscope 101, or the entire stethoscope 101). In some embodiments that perform the cleaning process using ultraviolet light, the cleaning member 104 includes a germicidal ultraviolet lamp 125 (see FIG. 2C) that irradiates the piece of equipment (e.g., the chestpiece 103) with ultraviolet light at a short enough wavelength to kill or inactivate microorganisms present on the chestpiece 103. In some embodiments that perform the cleaning process using ultraviolet light, the cleaning member 104 includes at least one germicidal ultraviolet light-emitting diode (LED) that irradiates the piece of equipment (e.g., the stethoscope 101) with ultraviolet light at a short enough wavelength to kill or inactivate microorganisms present on the stethoscope 101. Exemplary embodiments that perform the cleaning process using ultraviolet light may not include the cleaning solution chamber 105.

According to exemplary embodiments of the present invention, the compliance-based cleaning device 100 may include a first cleaning member 104 including the plurality of holes 106 and the cleaning solution chamber 105 to implement a first cleaning process utilizing a liquid cleaning solution, as well as a second cleaning member 104 (e.g., a germicidal ultraviolet lamp) to implement a second cleaning process utilizing ultraviolet light. The compliance-based cleaning device 100 may allow a user to select one of the first and second cleaning methods to perform, or both of the first and second cleaning methods.

A compliance sensor 107 (e.g., a chestpiece sensor) may be disposed within the receiving area 102 of the compliance-based cleaning device 100. The compliance sensor 107 detects insertion of the piece of equipment (e.g., the chestpiece 103) into the receiving area 102, which allows for the cleaning process to automatically occur upon the chestpiece 103 being inserted into the receiving area 102. Alternatively, the cleaning process may be started manually by the medical practitioner by, for example, pressing a button, lever, switch, etc.

The compliance sensor 107 may be, for example, a proximity sensor that detects the presence of the piece of equipment (e.g., the chestpiece 103) in the receiving area 102 without physically contacting the chestpiece 103. The proximity sensor may be, for example, an inductive sensor, a capacitive sensor, a photoelectric sensor such as an infrared sensor, a through-beam sensor, a retro-reflective sensor, a diffuse sensor, or an ultrasonic sensor. Alternatively, the compliance sensor 107 may be, for example, a physical sensor that detects the presence of the chestpiece 103 in the receiving area 102 via establishing physical contact with the chestpiece 103 (e.g., a switch that is activated upon the chestpiece 103 pressing/depressing the switch). Alternatively, the cleaning device 100 may include a user input 108 (e.g., a button, switch, lever, etc.) allowing the user to manually begin the cleaning process. Exemplary embodiments may include both the compliance sensor 107 and the user input 108, or one of the compliance sensor 107 and the user input 108.

According to exemplary embodiments, the duration of the cleaning process may be, for example, a pre-set amount of time or a user-defined amount of time, or the cleaning process may be performed for the entire amount of time that the piece of equipment (e.g., the chestpiece 103) is detected as being disposed within the receiving area 102 of the compliance-based cleaning device 100. According to exemplary embodiments, the cleaning process may be performed a single time (e.g., the chestpiece 103 or stethoscope 101 may be continuously sprayed with the liquid cleaning solution, or irradiated with ultraviolet light, for a pre-set number of seconds or for the entire time that the chestpiece 103 or stethoscope 101 is disposed within the receiving area 102 or the cleaning area 803) or multiple times (e.g., the chestpiece 103 or stethoscope 101 may be sprayed once every first pre-set number of seconds, or irradiated with ultraviolet light every first pre-set number of seconds, for a total duration of a second pre-set number of seconds).

The compliance-based cleaning device 100 includes a compliance component 110. The compliance component 110 may be, for example, a camera, or a radio-frequency identification (RFID) reader such as, for example, a near field communication (NFC), as described in further detail below. The compliance component 110 allows for the monitoring of the cleaning processes performed by the compliance-based cleaning device 100. For example, the compliance component 110 allows for the tracking and recording of cleaning processes relative to a specific piece of equipment (e.g., a specific stethoscope 101). For example, every time a cleaning process is performed on a stethoscope 101 by the compliance-based cleaning device 100, the compliance component 110 monitors the cleaning process and obtains identifying information (e.g., information included in, for example, readable indicia disposed on the stethoscope 101, as described below). Once the identifying information has been obtained, compliance data (e.g., cleaning process records) based on the identifying information may be created and transmitted from the compliance-based cleaning device 100 to a compliance database 1000 via, for example, a network component 111 of the compliance-based cleaning device 100. The network component 111 may be, for example, a wired network component (e.g., an Ethernet interface) or a wireless network component (e.g., a WiFi transceiver, a cellular transceiver, etc.). The compliance component 110 may be implemented in a variety of manners and may include a plurality of sub-components (e.g., multiple cameras, scanners, etc.) as described in further detail below. The compliance component 110 may be placed at a variety of locations in proximity with the receiving area 102 or the cleaning area 803 based on the type of equipment being cleaned and the expected location of readable indicia on the piece of equipment being cleaned relative to the receiving area 102 or the cleaning area 803.

In an exemplary embodiment, the compliance component 110 includes a camera. The camera is utilized to capture readable indicia 116 (see FIG. 3 ) disposed on the stethoscope 101. As described above, the readable indicia 116 may be, for example, a serial number, a registration number, a barcode, etc. that is disposed on the piece of equipment being cleaned (e.g., the chestpiece 103 of the stethoscope 101, the stethoscope 101, or other equipment). The readable indicia stores/includes a unique identifier capable of uniquely identifying the piece of equipment (e.g., the stethoscope 101). The readable indicia 116 may be located on the chestpiece 103 of the stethoscope 101. Once inserted into the receiving area 102 of the compliance-based cleaning device 100, the camera may locate and capture the readable indicia 116 and record the unique identifier stored in the readable indicia 116. The camera may include low-light capture functionality, allowing the camera to adequately capture the readable indicia 116 while it is in the receiving area 102.

The readable indicia 116 may be identified using, for example, optical character recognition (OCR). In an exemplary embodiment, OCR may be performed, for example, at the compliance-based cleaning device 100. For example, the compliance-based cleaning device 100 may include a processor 115 that may perform an OCR algorithm. Alternatively, the captured readable indicia 116 may be transmitted as a raw image to a server 1001 (e.g., a server 1001 including the compliance database 1000) that is part of a compliance-based cleaning system 1005, and OCR may be performed at the server 1001. The compliance-based cleaning system 1005 according to an exemplary embodiment of the present invention is shown in FIG. 6 .

The identifying information read from the readable indicia 116 may be immediately transmitted to the compliance database 1000 via the network component 111 upon being obtained by the camera. Alternatively, the identifying information read from the readable indicia 116 may be stored in a memory 113 of the compliance-based cleaning device 100 and may later be transmitted to the compliance database 1000. For example, in an exemplary embodiment, each time a piece of equipment (e.g., the chestpiece 103 of a stethoscope 101 or the stethoscope 101) is cleaned in the compliance-based cleaning device 100, a cleaning record based on the identifying information read from the readable indicia 116 may be generated by the compliance component 110 and stored in the memory 113. The plurality of stored cleaning records (e.g., cleaning records corresponding to each time a piece of equipment is cleaned in the compliance-based cleaning device 100) may then be transmitted to the compliance database 1000 at a pre-defined time (e.g., all cleaning records may be transmitted to the compliance database 1000 at the end of the day). In an exemplary embodiment, the memory 113 may be utilized to temporarily store cleaning records in the event that the network connection between the compliance-based cleaning device 100 and the compliance database 1000 is not present (e.g., in the event of a network outage).

In an exemplary embodiment, the compliance component 110 includes a radio-frequency identification (RFID) reader such as, for example, a near field communication (NFC) reader, and the readable indicia 116 includes an RFID tag such as, for example, an NFC tag. The NFC tag may be placed on the piece of equipment being cleaned (e.g., the chestpiece 103 of the stethoscope 101, the stethoscope 101, or other equipment), allowing for equipment that does not otherwise include readable 116 indicia such as a serial number, a registration number, a barcode, etc. to be identified by the compliance component 110. Once the NFC tag is read by the NFC reader, a cleaning record(s) based on identifying information stored in the NFC tag may be utilized in a similar manner as described above.

As described above, the compliance database 1000 stores a plurality of cleaning records. The cleaning records may include a plurality of different types of identifying information, resulting in the formation of a robust database that promotes compliance and establishes a record of compliance and non-compliance. For example, as described above, when a cleaning process is performed on a piece of equipment (e.g., a stethoscope 101), compliance data is created. The compliance data includes identifying information obtained by the compliance component 110 of the compliance-based cleaning device 100. This identifying information may be used to create the cleaning records stored in the compliance database 1000.

Identifying information obtained by the compliance component 110 and stored in the cleaning records in the compliance database 1000 may include, for example, (i) identifying information that identifies the piece of equipment (e.g., the stethoscope 101) that has been cleaned, (ii) identifying information that identifies the compliance-based cleaning device 100 used to perform the cleaning, and/or (iii) identifying information that identifies the medical practitioner that performed the cleaning. The cleaning records may further include information identifying, for example, a time at which a cleaning process was performed, or identifying information that indicates whether the medical practitioner sanitized his or her hands at substantially the same time that the piece of equipment was cleaned (e.g., at exactly the same time, or within a short amount of time that is long enough to clean both the piece of equipment and the medical practitioner's hands), as described in further detail below. The identifying information relating to the medical practitioner may be obtained using, for example, an identification camera 117 and/or a scanner 118. The scanner 118 may include, for example, a fingerprint scanner and/or an identification card scanner included as part of the compliance component 110, as described in further detail below.

According to an exemplary embodiment, each cleaning record stored in the compliance database 1000 includes a plurality of pieces of identifying information. For example, each cleaning record may include identifying information corresponding to a unique identifier indicating the compliance-based cleaning device 100 used for that particular cleaning process. For example, a location such as a hospital may utilize a plurality of compliance-based cleaning devices 100 located throughout the hospital, and each compliance-based cleaning device 100 may have a unique identifier, allowing the hospital to determine which compliance-based cleaning devices 100 performed which cleaning processes. Each cleaning record may further include identifying information corresponding to a unique identifier indicating the piece of equipment (e.g., the stethoscope 101) cleaned during that particular cleaning process. This unique identifier may be included in the readable indicia 116 of the stethoscope 101, as described above. Each cleaning record may further include identifying information corresponding to a unique identifier indicating a medical practitioner that performed the cleaning. According to exemplary embodiments, each cleaning record may include additional pieces of identifying information such as, for example, a unique identifier indicating a medical practitioner to whom the corresponding compliance-based cleaning device 100 is assigned/registered, a primary location (e.g., a hospital) at which the corresponding compliance-based cleaning device 100 is located, and a secondary location (e.g., a room in a hospital identified by, for example, a room number) at which the corresponding compliance-based cleaning device 100 is located.

Utilization of the compliance-based cleaning device 100 allows for entities (e.g., hospitals, other medical institutions, insurance companies, government agencies, etc.) to implement forced compliance relating to the cleaning of equipment/tools/devices (e.g., stethoscopes 101). For example, although the regular cleaning of stethoscopes 101 is typically suggested/required in order to prevent the spread of germs, bacteria, viruses, fungus, etc. among patients, medical practitioners using a stethoscope often do not comply with such cleaning suggestions/requirements. As a result, patients on which a stethoscope 101 is used may be unnecessarily exposed to germs, bacteria, viruses, fungus, etc., and thus, may risk contracting sicknesses or diseases, which could have potentially been avoided had the stethoscope 101 used on the patients been properly cleaned. Through the use of the compliance-based cleaning device 100 according to exemplary embodiments of the present invention, compliance and non-compliance relating to cleaning may be accurately tracked, verified and documented, improving cleaning compliance and establishing records for institutional, hospital, facility, office, governmental and other action in the face of non-compliance. In addition to a database of compliance and non-compliance, exemplary embodiments of the present invention allow for entries directly into a patient's electronic medical records (EMRs) and allows for documentary support for billing, consistent with existing and developing requirements of commercial insurers and governmental payors.

In an exemplary embodiment, an entity (e.g., a hospital) may choose to register every piece of equipment (e.g., every stethoscope 101) for which forced compliance is to be implemented that belongs to the hospital in the compliance database 1000. For convenience of description, this entity will be described herein as a hospital, however, it is to be understood that the entity is not limited thereto. For example, the entity may be a doctor's office, an ambulatory surgery center, a nursing facility, a rehabilitation facility, another medical institution, an insurance company, a government agency, etc. The compliance database 1000 may be managed by a third party entity or by the hospital itself. Thus, the compliance database 1000 may be located at the hospital, or at a location remote from the hospital (e.g., at a location managed by the third party entity). Interplay between the compliance-based cleaning device 100 and the compliance database 1000 may be functionally the same regardless of the location of the compliance database 1000. Alternatively, the hospital may choose to register every stethoscope 101 belonging to the hospital to a location in the hospital, such as to a specific room in the hospital. Registering every stethoscope 101 in the hospital in the compliance database 1000 allows for cleaning processes relating to each stethoscope 101 to be accurately tracked.

As described above, in addition to cleaning records including information indicating the tool/equipment/device (e.g., the stethoscope 101) that has been cleaned and information indicating the compliance-based cleaning device 100 used to perform the cleaning, cleaning records may further include information indicating the owner or user (e.g., the medical practitioner) that is associated with a specific tool/equipment/device (e.g., the stethoscope 101) or performed the cleaning. The identifying information indicating the medical practitioner that is associated with or performed the cleaning may be obtained in a variety of manners.

For example, in an exemplary embodiment, the compliance component 110 may include an identification camera 117. Each time a cleaning process is performed by the compliance-based cleaning device 100, the identification camera 117 may capture an image of the medical practitioner that performed the cleaning process. The identification camera 117 may include pan/tilt/zoom functionality, and may automatically identify the position and pose of the medical practitioner's face. The captured image may be stored in the compliance database 1000 and linked to the identifying information indicating the piece of equipment (e.g., the stethoscope 101) that was cleaned and/or the compliance-based cleaning device 100 that performed the cleaning.

The medical practitioner also may be identified using, for example, a fingerprint scanner included as a part of the compliance component 110, or an identification card scanner (e.g., a barcode scanner, a camera, an RFID reader, etc.) included as a part of the compliance component 110 that is configured to read the medical practitioner's identification card/badge. The fingerprint scanner and the identification card scanner may be combined into a single component (e.g., the scanner 118 shown in FIG. 1 ), or they may be separate components.

According to exemplary embodiments, the compliance database 1000 may store a plurality of reference records corresponding to the plurality of pieces of identifying information collected by the compliance-based cleaning device 100. The reference records may be registered by the entity that manages the compliance database 1000 (e.g., a hospital or a third party entity, as described above). Identifying information collected by the compliance-based cleaning device 100 may be compared to corresponding reference records stored in the compliance database 1000 for identification purposes.

For example, a picture of each medical practitioner working in a hospital may be stored in the compliance database 1000 as reference records. When a cleaning process is performed and a picture of the medical practitioner is captured, as described above, the captured picture may be transmitted to the compliance database 1000 and compared to the reference records to identify the medical practitioner that performed the cleaning process. Various types of image/facial recognition algorithms may be utilized to identify the medical practitioner. A similar process of utilizing reference records to perform a comparison and identification operation may be used for other types of identifying information collected by the compliance-based cleaning device 100.

Exemplary embodiments may not utilize reference records and/or image/facial recognition algorithms. These exemplary embodiments may still capture a picture of medical practitioners as cleaning processes are performed. In these exemplary embodiments, the images captured may be stored in the compliance database 1000 without performing a comparison operation, and may be utilized to identify a medical practitioner as needed to, for example, support compliance, billing activities, etc., by referring to the stored records as needed.

Exemplary embodiments that utilize identifying information indicating the medical practitioner that performed a cleaning process may implement a notification system to transmit notifications to the medical practitioners. For example, in exemplary embodiments in which reference records corresponding to medical practitioners are stored in the compliance database 1000, contact information associated with each medical practitioner may also be stored. This contact information may include, for example, a medical practitioner's email address, phone number, pager number, address, etc. A notification may be transmitted from the compliance-based cleaning system 1005 to the medical practitioner upon the occurrence of certain events.

Notifications may correspond to warnings issued to medical practitioners. For example, a notification may be sent when a medical practitioner has not cleaned a piece of equipment (e.g., a stethoscope 101) registered to the medical practitioner within a predefined amount of time, when the medical practitioner is in danger of being disciplined for non-compliance, etc. The notifications may be, for example, an email, a phone call, a text, a letter, etc., and records of the notifications may be kept in the compliance database 1000. The notifications may also be transmitted to entities other than the medical practitioners such as, for example, an infection control department in a hospital, a third party entity, a government agency, etc.

The compliance-based cleaning device 100 may include a variety of physical configurations according to exemplary embodiments of the present invention.

The compliance-based cleaning device 100 described with reference to FIGS. 8 to 26 may include some or all of the components described above, including the components illustrated in FIG. 5 .

According to an exemplary embodiment, the compliance-based cleaning device 100 includes a sanitization chamber 1700 (see FIGS. 17-19 and 22-23 ) having a cleaning area 803 shaped and dimensioned to receive the stethoscope 101. Although a stethoscope 101 is used as an example of the piece of equipment to be cleaned with reference to FIGS. 8 to 26 , exemplary embodiments are not limited thereto.

The device 100 may include a rotating door 801 (also referred to herein as a revolving door) including a hands-free door lever 802 (also referred to herein as a door handle) (see FIGS. 8 to 10 and 26 ). The user may swivel the rotating door 801 in a first direction DR1 (see FIG. 10 ) to expose the cleaning area 803, and may insert the stethoscope 101 into the exposed cleaning area 803 (see FIGS. 8 and 9 ). The user may then swivel the rotating door 801 in a second direction DR2 opposite to the first direction DR1 (see FIG. 10 ) to close the sanitization chamber 1700, enclosing the stethoscope 101 within the compliance-based cleaning device 100. Once the rotating door 801 has been closed, a cleaning process may be performed on the stethoscope 101. For example, in an exemplary embodiment, the compliance-based cleaning device 100 may perform the cleaning process using a light-emitting device (e.g., at least one ultraviolet light-emitting diode (LED)) that emits an ultraviolet light within the cleaning area 803 to irradiate the stethoscope 101 with ultraviolet light.

The design of the rotating door 801 allows for the compliance-based cleaning device 100 to be used in a hands-free manner. For example, the user may swivel the rotating door 801 open and closed using his or her elbow, back of the hand, etc., thus avoiding contact between the user's palm and fingers and the compliance-based cleaning device 100. As a result, the user may be prevented from contaminating the compliance-based cleaning device 100 and from being contaminated by the compliance-based cleaning device 100.

The piece of equipment to be cleaned (e.g., the stethoscope 101) may be mounted within the cleaning area 803 of the sanitization chamber 1700. In an exemplary embodiment, when the compliance-based cleaning device 100 is adapted to clean the stethoscope 101, the device 100 may include a plurality of mounting hooks 804 hanging from an upper surface of the sanitization chamber 1700 (see FIGS. 8 to 9, 14, 17 to 18 and 20 ). The stethoscope 101 may be stably affixed within the cleaning area 803 by way of at least a portion of the stethoscope 101 being hung over at least one of the plurality of mounting hooks 804.

For example, in an exemplary embodiment, the plurality of mounting hooks 804 may include three different mounting hooks 804 (see FIGS. 14, 17 and 18 ). The end of one ear tube near one earpiece of the stethoscope 101 may be hung over a first mounting hook 804 (e.g., the leftmost mounting hook 804 in FIGS. 14, 17 and 18 ). This mounting hook 804 may also be referred to herein as an earpiece mounting hook 804. The end of the other ear tube near the other earpiece of the stethoscope 101 may be hung over a second mounting hook 804 (e.g., the rightmost mounting hook 804 in FIGS. 14, 17 and 18 ). This mounting hook 804 may also be referred to herein as an earpiece mounting hook 804. The chestpiece 103 of the stethoscope 101 may be hung over a third mounting hook 804 (e.g., the center mounting hook in FIGS. 14, 17 and 18 ). This mounting hook may be referred to herein as a chestpiece mounting hook 804. The left earpiece mounting hook 804, the chestpiece mounting hook 804, and the right earpiece mounting hook 804 may be separate components that are each connected to the upper surface of the sanitization chamber 1700 and are not directly connected to each other.

The plurality of mounting hooks 804 may be affixed to and extend downward from the upper surface of the sanitization chamber 1700. The shape and configuration of the earpiece mounting hooks 804 may be different from the shape of the chestpiece mounting hook 804. For example, the earpiece mounting hooks 804 may be attached to the upper surface of the sanitization chamber 1700 at a single point, may extend downward in a substantially straight line, and then may curve at least one time, as shown in the figures, thereby forming a hook for the ear tubes near the earpieces of the stethoscope 101 to be mounted thereon. In a different manner, in an exemplary embodiment, the chestpiece mounting hook 804 may be attached to the upper surface of the sanitization chamber 1700 at two points, and may curve in a shape as shown in the figures that is configured to allow the chestpiece of the stethoscope 101 to be mounted thereon.

The mounting hooks 804 may be formed of a bent wire, which may be formed of stainless steel and coated in polytetrafluoroethylene (PTFE). Forming the mounting hooks 804 of stainless steel and coating the mounting hooks 804 in PTFE may provide the characteristics of corrosion resistance and nonreactivity, thus allowing for easy cleaning and maintenance of the compliance-based cleaning device 100. The mounting hooks 804 may further be polished to increase reflectivity (e.g., to more effectively reflect and transmit ultraviolet light emitted within the cleaning area 803 during cleaning).

To sanitize the stethoscope 101, the user may open the rotating door 801 via the door handle 802 using a part of the body other than his or her palm/fingers, mount the stethoscope 101 to the mounting hooks 804, and close the rotating door 801 without using his or her palm/fingers. In an exemplary embodiment, the cleaning process automatically begins upon the rotating door 801 being closed after being opened. The cleaning process is described in further detail below.

An indicator such as, for example, a light-emitting diode (LED) visible to the user, may indicate the current status of the compliance-based cleaning device 100. For example, an LED 805 (also referred to as an externally facing LED 805) may indicate the current mode of the compliance-based cleaning device 100 (see FIGS. 8 to 10 and 13 to 14 ), as described further below.

In an exemplary embodiment as shown in the figures, the LED 805 is disposed as an LED strip on an upper front portion of the compliance-based cleaning device 100 above the rotating door 801. The LED 805 may change colors to indicate different statuses. In addition, the location at which the LED 805 lights up may also indicate different statuses.

For example, in an exemplary embodiment, when looking at the compliance-based cleaning device 100 from the front, the left side of the LED 805 may be turned on and made green to indicate that the device is in a “ready” mode. The LED 805 may remain green whenever the door 801 is open, indicating that the device 100 is ready to receive the stethoscope 101. When the door 801 is closed, the cleaning process may automatically begin. When this occurs, the left side of the LED 805 may be turned off, and the right side of the LED 805 may be turned on and made red to indicate that the device 100 is currently in a “cleaning” mode and that the door 801 should not be opened. Once the cleaning process is completed, the right side of the LED 805 may be turned off, and the left side of the LED 805 may be turned on and made green again, indicating to the user that the cleaning process is complete and that the stethoscope 101 may be removed from the device 100.

In an exemplary embodiment, the LED 805 may gradually light up in the horizontal direction to indicate the progress of the cleaning process. For example, the LED 805 may change from red to green in a direction from the left to the right of the compliance-based cleaning device 100 when a cleaning process begins, and continue until it is finished, providing the user with the real-time status of the cleaning process.

In an exemplary embodiment, a counter 806 (see FIGS. 9, 12 and 15 ) may be disposed on the compliance-based cleaning device 100. The counter 806 may track the number of times the device 100 performs a cleaning process, and may be disposed at a location on the device 100 that is visible to the user, as seeing the usage numbers may motivate the user to use the device 100 more frequently. The counter 806 may be, for example, a digital counter that displays a numerical value indicating the number of cleaning processes performed. Although the counter 806 is disposed on the left side of the compliance-based cleaning device 100 in the figures (when looking at the device 100 from the front), the location of the counter 806 is not limited thereto. A reset button 807 (see FIG. 16 ) may be utilized to reset the counter. The reset button 807 may be placed on the back of the compliance-based cleaning device 100, thereby preventing users from resetting the counter 806, either intentionally or unintentionally, when the device 100 is mounted (e.g., to a wall). However, the location of the reset button 807 is not limited thereto.

According to exemplary embodiments, the counter 806 may track each time the rotating door 801 is closed and/or each time a cleaning process is performed. Such tracking may be performed using a switch 2400 (see FIGS. 25 and 26 ) that is activated each time the rotating door 801 is closed and makes contact with the switch 2400.

According to an exemplary embodiment, the compliance-based cleaning device 100 may include the sanitization chamber 1700 and an internal housing 1900 (see FIGS. 17 to 23 ). The sanitization chamber 1700 is coupled to the internal housing 1900, and when coupled and the rotating door 801 is closed, encloses the cleaning area 803 which is shaped and dimensioned to receive the stethoscope 101 within the compliance-based cleaning device 100. For example, the stethoscope 101 may be placed into the cleaning area 803 when the rotating door 801 is open, and the rotating door 801 may then be swiveled to be closed, thus, swiveling the position of the stethoscope 101 such that instead of facing the open front of the device 100, the stethoscope 101 faces a cylindrical rear wall 1902 (also referred to as a cylindrical inner surface) of the internal housing 1900. The sanitization chamber 1700 may transition between an open position, in which the cleaning area 803 is visible to the user, and a closed position, in which the cleaning area 803 is not visible to the user and the stethoscope 101 is enclosed within the compliance-based cleaning device 100, by rotating about an axis (e.g., a vertical axis) within the internal housing 1900.

For example, the shape of the sanitization chamber 1700 may be cylindrical and may be defined by a cylindrical sidewall 1701 (which corresponds to the door 801 when the door is closed and visible to the user). The cylindrical sidewall 1701 may also be referred to as a cylindrical inner surface. The shape of the cylindrical sidewall 1701 of the sanitization chamber 1700 may correspond to the shape of the cylindrical rear wall 1902 of the internal housing 1900 (e.g., the curvature of the cylindrical sidewall 1701 may be about the same as the curvature of the cylindrical rear wall 1902, and may be, for example, a semicircle having a curvature of about 180 degrees). The surfaces of the cylindrical rear wall 1902 of the internal housing 1900 and the cylindrical sidewall 1701 of the sanitization chamber 1700 that face the stethoscope 101 during the cleaning process may each be formed of a reflective material.

The cylindrical sidewall 1701 of the sanitization chamber 1700 is attached to a top semicircular surface 1705 and a bottom semicircular surface 1702 of the sanitization chamber 1700 (see FIGS. 17, 18 and 26 ). The top semicircular surface 1705 may include a top mounting component 1703 (e.g., an axle or disc) and the bottom semicircular surface 1702 may include a bottom mounting component 1704 (e.g., an axle or disc) (see FIGS. 17, 18 and 26 ).

The internal housing 1900 may include a top surface 1903 and a bottom surface 1904 (see FIGS. 19 and 20 ). The top surface 1903 may include a top mounting component 1906 and the bottom surface 1904 may include a bottom mounting component 1905 (see FIGS. 19 and 21-26 ). The top and bottom mounting components 1906 and 1905 may each be, for example, a pocket or hole into which the corresponding mounting components 1703 and 1704 (e.g., axles) of the sanitization chamber 1700 fit into and are matingly coupled with.

For example, in an exemplary embodiment, the mounting components 1703 and 1704 of the sanitization chamber 1700 are axles (e.g., a top axle 1703 and a bottom axle 1704), the mounting components 1906 and 1905 of the internal housing 1900 are pockets (e.g., a top pocket 1906 and a bottom pocket 1905) , and the axles 1703 and 1704 are matingly received into and coupled with the pockets 1906 and 1905, respectively. When coupled, the axles 1703 and 1704 and the pockets 1906 and 1905 allow for the user to use the door handle 802 to rotate the sanitization chamber 1700 within the internal housing 1900 to transition between the open and closed positions while the internal housing 1900 remains stationary. Such rotation occurs about an axis defined by the axles 1703 and 1704 and the pockets 1906 and 1905 (e.g., about an axis corresponding to an imaginary straight vertical line extending along the axles 1703 and 1704 and the pockets 1906 and 1905).

The compliance-based cleaning device 100 may include a cleaning member 104, which is located in proximity to the sanitization chamber 1700 and performs a cleaning process on the stethoscope 101 in response to the sanitization chamber 1700 entering the closed position. The cleaning member 104 may include, for example, at least one ultraviolet light-emitting device (e.g., an ultraviolet light-emitting diode (LED)) that irradiates the stethoscope 101 with an ultraviolet light when the sanitization chamber 1700 is in the closed position and the cleaning process is being performed.

In an exemplary embodiment, the at least one ultraviolet light-emitting device is one of a plurality of ultraviolet light-emitting devices 1901, which may be disposed on the cylindrical rear wall 1902 of the internal housing 1900 (see FIGS. 19 and 21 to 23 ). When the sanitization chamber 1700 transitions into the closed position from the open position, the ultraviolet light-emitting devices 1901 turn on, and thus, light emitted from the light-emitting devices 1901 irradiates the stethoscope 101 to clean the stethoscope 101. Then, when the sanitization chamber 1700 transitions out of the closed position and into the open position, thus signaling the end of the cleaning process, the ultraviolet light-emitting devices 1901 are turned off.

The ultraviolet light-emitting devices 1901, as well as the externally facing LED 805, may be controlled by a timer relay such that the ultraviolet light-emitting devices 1901 and the externally facing LED 805 turn on/off at the appropriate times corresponding to the cleaning process being performed. The timer relay may be adjustable and may be programmed to correspond to a desired time taken to complete the sanitization cycle/cleaning process, and the timer relay may be activated (and begin the countdown of the programmed time) when the door 801 transitions from the open position to the closed position. For example, the timer relay may work in conjunction with a switch 2400 (see FIGS. 25 and 26 ) to turn the ultraviolet light-emitting devices 1901 and the externally facing LED 805 on/off when the switch 2400 makes contact with the door 801 when the door is closed.

When the plurality of ultraviolet light-emitting devices 1901 are utilized, the light-emitting devices 1901 may be spaced apart from each other at regular intervals, thereby providing uniform irradiation of the stethoscope 101 during the cleaning process.

As a result of the cylindrical shape and reflective material of the cylindrical rear wall 1902 of the internal housing 1900 and the cylindrical sidewall 1701 of the sanitization chamber 1700, as well as the placement of the plurality of ultraviolet light-emitting devices 1901, when the sanitization chamber 1700 is in the closed position, efficient ultraviolet exposure of the stethoscope 101 during the cleaning process may be achieved. For example, according to exemplary embodiments, when the rotating door 801 is closed, thus enclosing the stethoscope 101 within the sanitization chamber 1700 such that it is enclosed by the cylindrical sidewall 1701 of the sanitization chamber 1700 and the cylindrical rear wall 1902 of the internal housing 1900, the internal volume of the sanitization chamber 1700 creates a 360° reflective chamber which increases the reflectivity and efficacy of the ultraviolet light-emitting devices 1901, thereby reducing the duration of the cleaning process that is needed to adequately sanitize the stethoscope 101.

As described above, the compliance-based cleaning device 100 described with reference to FIGS. 8 to 26 may include some or all of the components illustrated in FIG. 5 . For example, in an exemplary embodiment, the compliance-based cleaning device 100 may further include the compliance component 110, which as described above, monitors the cleaning process performed on the stethoscope 101, and the network component 111, which as described above, transmits the compliance data to the compliance database 1000 in response to the cleaning member 104 performing the cleaning process on the stethoscope 101. As described above, the compliance data may include identifying information obtained by the compliance component 110. For convenience of explanation, a repeated detailed description of such components and functionality previously described above is omitted.

According to exemplary embodiments, the compliance-based cleaning device 100 may include a first mounting hole 808, a stability bracket 809 and a second mounting hole 810 disposed on the stability bracket 809.

During installation, the user may install a coupling member such as, for example, a bolt into a surface such as a wall (e.g., into a stud), or an anchor into the wall, and then may slide the compliance-based cleaning device 100 over the coupling member to mount the device 100 on the wall. Once installed onto the wall via the first mounting hole 808, the user may then further secure the compliance-based cleaning device 100 to the wall by installing another coupling member through the second mounting hole 810. As shown in the figures, in an exemplary embodiment, the first and second mounting holes 808 and 810 may be vertically aligned with one another on the back of the compliance-based cleaning device 100. However, the location and number of the mounting holes are not limited thereto. The stability bracket 809 is a flange extending downward below the compliance-based cleaning device's 100 body, which may further stabilize the device 100 against the surface to which it is mounted (e.g., to a wall).

The coupled sanitization chamber 1700 and internal housing 1900 may be enclosed by an external enclosure 811, which protects the internal components of the compliance-based cleaning device 100.

In an exemplary embodiment, the compliance-based cleaning device 100 may be a portable freestanding unit. The portable freestanding compliance-based cleaning device 100 may be easily transported between locations. Alternatively, the compliance-based cleaning device 100 may include attachment means such as, for example, a holster or belt clip 401, as shown in FIGS. 4A-4B, allowing the device 100 to be carried by the medical practitioner. Alternatively, the compliance-based cleaning device 100 may be mounted to a surface such as, for example, a table, desk, wall, etc. The device 100 may include a battery 120 (e.g., a rechargeable battery) and/or may receive power via a standard electrical outlet connection.

FIG. 1E show a compliance-based cleaning device including a hand sanitizing component according to an exemplary embodiment of the present invention.

Referring to FIG. 1E, according to an exemplary embodiment of the present invention, the compliance-based cleaning device 100 further includes a hand sanitizing component 121. As described above, the chestpiece 103 of the stethoscope 101 and a medical practitioner's hands are typically the two greatest causes of the spread of germs, bacteria, viruses, fungus, etc. Inclusion of the hand sanitizing component 121 in the compliance-based cleaning device 100 promotes regular hand cleaning in addition to the cleaning of the piece of equipment (e.g., the stethoscope 101). In an exemplary embodiment, when the medical practitioner inserts the piece of equipment (e.g., the chestpiece 103 of the stethoscope 101) into the receiving area 102 of the compliance-based cleaning device 100, the medical practitioner also places his or her hand(s) in proximity to the hand sanitizing component 121. The hand sanitizing component 121 is connected to a hand sanitizing solution chamber 122 that stores a hand sanitizing solution. The hand sanitizing solution may be, for example, a hand sanitizing gel, an alcohol solution (e.g., about 70% isopropyl alcohol), etc. The hand sanitizing solution may be dispersed automatically in response to the medical practitioner inserting his or her hands into the hand sanitizing component 121 through the use of a sensor similar to the compliance sensor 107, or may be manually dispersed in response to the medical practitioner pressing a button, lever, switch, etc.

In exemplary embodiments that include the hand sanitizing component 121, the compliance data transmitted to the compliance database 1000 may include identifying information indicating whether the medical practitioner sanitized his or her hands. The identification camera 117 and/or the scanner 118 (e.g., a fingerprint scanner and/or an identification card scanner) may be utilized in conjunction with the hand sanitizing component 121 to identify the medical practitioner. Including the hand sanitizing component 121 in the same device (e.g., the compliance-based cleaning device 100) that cleans the piece of equipment (e.g., the stethoscope 101) provides a reminder to the medical practitioner to clean his or her hands every time he or she cleans the piece of equipment. Further, including the hand sanitizing component 121 in the compliance-based cleaning device 100 provides a verifiable and documented process to monitor and track the cleaning of a medical practitioner's hands and the piece of equipment being cleaned together in one efficient, verifiable, documented compliance-based process.

It is to be understood that the hand sanitizing component 121 and hand sanitizing solution chamber 122 shown in FIG. 1E may also be included in the compliance-based cleaning device 100 of FIGS. 1A-1D.

In an exemplary embodiment, rather than transmitting the compliance data from the compliance-based cleaning device 100 to the compliance database 1000, the compliance data may be stored in the memory 113 of the compliance-based cleaning device 100 and manually retrieved at a later time.
